The AirTAC GFR200-08 AirTAC Filter Regulator 1/4 in PT, Manual Drain is a genuine G-series filter regulator: water separation, 40 µm particulate filtration and balanced-type pressure regulation combined in a single body. It has PT1/4" ports, a manual drain and regulates 0.05 - 0.9 MPa (7 - 130 psi). It does not lubricate — add a GL lubricator, or order the GFC two-unit set, if downstream equipment needs oil.
The AirTAC GFR200-08 is a compact filter regulator that removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration is the 200 size with a 1/4 in PT port, a manual drain on the PC bowl, the standard 40 um filter element, and a round external gauge with a psi scale, so you can read the regulated outlet pressure directly at the unit. The regulator is the standard type with an adjustment range of 0.05-0.9 MPa (7-130 psi), and maximum inlet pressure is 1.0 MPa (145 psi).
This is a genuine AirTAC part. The GFR series is available in sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and with options including automatic or differential-pressure drains, a 5 um filter element (code W), square or round gauges with MPa, psi or bar scales, G or NPT threads, and a mounting bracket. Flow is published in the catalogue as curves rather than a single rated figure, so we confirm the datasheet and sizing figures on request.

Specifications follow the official AirTAC G-series air-preparation data. The regulating band is set by the drain type: automatic and differential-pressure drains regulate 0.15 - 0.9 MPa, a manual drain regulates 0.05 - 0.9 MPa. Standard type, regulating 0.05 - 0.9 MPa (7 - 130 psi). Air must not freeze in the unit. Flow curves, weight and outline dimensions are not published in our data set — ask us and we will confirm from the factory datasheet.
| GFR200 | G-series filter regulator, 200 body — sets the port range. |
|---|---|
| 08 | Port size PT1/4". This body offers 06 = PT1/8", 08 = PT1/4". |
| M | Drain: Manual drain — this also sets the regulating band (0.05 - 0.9 MPa (7 - 130 psi)). |
| (blank) | Standard type. Blank is standard, L is the low-pressure type. |
| J | Supplied without bracket. |
| (blank) | Pressure gauge fitted (blank). |
| C | Gauge shape: Round. C is round, F is square. |
| 2 | Gauge scale: psi. 1 is MPa, 2 is psi, 3 is bar. |
| (blank) | Filtering grade 40 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| (blank) | PT thread. PT is the default; G is BSPP and T is NPT. |
| (blank) | No reverse-flow valve (the default). |
Field order is size, port, drain, type, bracket, gauge, shape, scale, grade, thread, reflux — a blank position takes the default. Example: GFR300-08 is a 300 body, PT1/4", differential drain, standard type, bracket included, gauge fitted, 40 µm, PT thread, no reflux valve.
A larger body carries a larger port and holds set pressure better as flow rises. AirTAC publishes flow only as curves, so size the body from your peak demand with headroom. The GFR600 uses an aluminium-alloy bowl; the 200, 300 and 400 bodies use PC.

Installed ahead of a directional-valve manifold on an assembly machine, it delivers filtered air at a set, stable pressure so solenoid valves and actuators see consistent supply conditions.
On a packaging or bottling line, it conditions the air feeding conveyor clamps and blow-off nozzles, keeping water and debris out of the circuit while holding the working pressure the line was set up for.
At a laboratory or test-bench air drop, it filters the shop supply and lets an operator dial in the exact regulated pressure a fixture or instrument needs, read directly on the psi gauge.
Start with the port and size step: this unit is the 200 size with a 1/4 in PT port, and the larger 300, 400 and 600 sizes step up in port and flow capacity, so match the size to the air demand of the circuit. Choose the drain to suit access: this version has a manual drain, which needs periodic draining by hand; automatic and differential-pressure drains are available if the unit will be hard to reach. The standard element is 40 um; specify the W option for 5 um filtration where downstream equipment needs cleaner air. Gauges are offered embedded square or external round, with MPa, psi or bar scales - this unit carries a round psi gauge. Threads can be ordered as PT (standard), G (BSPP) or NPT, and a mounting bracket is optional (this configuration has no bracket). Flow is published as curves, not a single rating, so ask us to confirm sizing against your application before ordering.
Quick checklist
The PC bowl must not be cleaned with solvents — wipe it with a dry cloth. Without the K option, air cannot flow back through the unit. A filter regulator adds no oil to the line.
AirTAC publishes flow for the GFR series as curves in the catalogue, not as a single rated number, so we do not quote a figure here. Contact us with your application details and we will confirm the flow and sizing data from the datasheet before you order.
The manual drain on this GFR200-08 means the PC bowl is emptied by hand, which suits points that are easy to reach during routine checks. If the unit will be mounted where access is difficult, the same size is available with an automatic or differential-pressure drain - just ask for that variant.
